Your thoughts on cleaning injectors

[Nilao]

Kerosene and cresylic acid? My great uncle was in ww2. There's also a home brew solution used in navy ships of the era. The stuff in the civilian world is known as Chen-dip carb cleaner. Nasty stuff for o-rings and seals though. Not sure how a diesel would fare burning it though. Spec 2-117 cleaner, rifle bore is what's in the cans in the garage from his gunsmith in days. I inherited all his stuff when he passed.
